Report which frontmatter keys exist in the vault, how often, and what they hold.
Every other frontmatter tool requires the key as an argument, which is only
answerable by someone who already knows the vault. This answers the question
that comes first — what is there to ask about — by enumeration rather than
ranking, so the result is exhaustive within its bounds rather than a best
guess.
The walk is bounded like every other whole-vault scan and refuses rather than
silently reporting a prefix: an inventory that quietly omits keys is worse
than no inventory, because a caller cannot tell the difference between "this
key does not exist" and "the scan stopped early".
Honors --exclude-glob / --read-paths: a key that occurs only in filtered
notes is not reported, exactly as its notes are not searchable.
